 limitations elsewhere contained in this Plan, an Executive Officer who
 terminates his employment with the Company and each Affiliated Employer on
 or after attaining his Normal Retirement Age and who was the President or
 a corporate Vice President of the Company as of the most recent date on
 which he performed service as an Executive Officer shall be entitled to a
 normal retirement benefit payable in the form of a single life annuity
 equal to the excess of:

     (a)  an amount equal to 50% of the Participant's Average Compensation,
          over

     (b)  the amount of the Participant's accrued Retirement Benefit under
          the Retirement Plan which would then be payable in the form of a
          single life annuity.

     4.2  NORMAL BENEFITS OF OTHER EXECUTIVE OFFICERS.  Subject to the
 limitations elsewhere contained in this Plan, an Executive Officer who
 terminates his employment with the Company and each Affiliated Employer on
 or after attaining his Normal Retirement Age and who was not the President

 which he performed service as an Executive Officer, shall be entitled to a
 retirement benefit payable in the form of a single life annuity determined
 in accordance with the formula set forth in section 4.1; provided,
 however, that in making such determination, the term "40% of the

 such benefit shall be reduced by .4166% for each full calendar month, from

 and including the month in which the Participant's 55th birthday occurs to
 the month in which his 62nd birthday occurs, by which the calendar month
 in which payment of the early retirement benefit provided for in this

     4.4  SURVIVING SPOUSE BENEFITS.  Subject to the limitations elsewhere
 contained in this Plan, the Surviving Spouse of a Participant who dies
 prior to commencement of any other benefit hereunder, including the
 Surviving Spouse of a former Participant who terminated employment because

 as of the last to occur of (1) the first day of the first month following
 the month in which the Participant's death occurs or (2) the date on which
 the Participant would have been eligible to receive payment of a benefit
 under section 4.3, or in the case of a Participant who terminated
 employment because of Disability, commencing as of the date on which the
 former Participant would have attained age 55, and such Surviving Spouse
 benefit shall be equal to 50% of the monthly benefit which would have been
 payable to the deceased Participant under this Plan if he had retired the
 day before his death and payment of his benefit had commenced on such date
 assuming, in the case of a former Participant who terminated employment
 because of a Disability, that the benefit payable to such former
 Participant at Normal Retirement Age under section 4.1 or 4.2, as
 applicable, would have been payable in reduced form at age 55 pursuant to
 section 4.3, and, assuming further, that in the case of a Participant or
 former Participant who died prior to attaining age 55 or prior to the date
 on which the Participant or former Participant had completed 10 years of
 Continuous Service, that a benefit would have been payable to such
 deceased Participant or former Participant as of the later of the dates
 described in (1) and (2), above; provided, however, that the benefit
 payable to the Surviving Spouse of a Participant or former Participant who
 died prior to the completion of 5 years of Continuous Service shall be
 reduced by 20% for each year of Continuous Service less than 5 accrued by
 such deceased Participant or former Participant.

     4.5  FORM, COMMENCEMENT AND DURATION OF PAYMENTS.

     (a)  A Participant may elect, subject to the approval of the Board of
          Directors, (1) to receive the Actuarial Equivalent of the benefit
          accrued by a Participant pursuant to section 4.1, 4.2 or 4.3 in
          any form of annuity payment option then available under the
          Retirement Plan or (2) to receive the value of the benefit
          accrued by a Participant pursuant to section 4.1, 4.2 or 4.3 in
          the form of a lump sum distribution.  In the event a Participant
          elects, with the approval of the Board of Directors, to receive a
          lump sum distribution of the value of the benefit otherwise
          provided for in section 4.1, 4.2, or 4.3, the value of the lump
          sum distribution under this Plan shall be determined in
          accordance with the provisions for determining the value of a
          lump sum distribution of the

                                   -6-

          Participant's Retirement Benefit under the terms of the
          Retirement Plan.

     (b)  Monthly benefit payments to the Participant (and, if applicable,
          his Surviving Spouse) under section 4.1, 4.2, 4.3 or 4.4, or a
          lump sum payment provided for under section 4.5(a) with respect
          to a benefit accrued under section 4.1, 4.2 or 4.3, shall
          commence on the first day of the month following the
          Participant's termination of employment or, if applicable, the
          date specified in section 4.4 as the date on which the
          Participant's Surviving Spouse became eligible for a Surviving
          Spouse benefit, and shall continue, subject to the provisions of
          section 4.7, until the month in which the death of the
          Participant (or, if applicable, his Surviving Spouse) occurs;
          provided, however, that a Participant or Surviving Spouse may
          elect to defer receipt of an early retirement benefit or
          Surviving Spouse benefit, as applicable, for any period of time
          not in excess of the date on which the Participant would have
          attained his Normal Retirement Age.  Despite any other provision
          of this Plan, a Participant who receives a benefit in the form of
          a lump sum distribution shall not be entitled to any monthly
          benefit otherwise provided for in this Plan.

     4.6  CHANGE OF CONTROL.

     (a)  In the event a Change of Control of the Company occurs, the
          Company shall pay to each Participant a lump sum amount equal to
          the present value of the Participant's accrued normal retirement
          benefit, as determined under section 4.1, as of the first day of
          the first month following such Change of Control of the Company
          on which such Participant is not an employee of the Company,
          whether or not such Change of Control of the Company occurred
          prior to the date on which such Participant shall have ceased to
          be an employee of the Company.  Upon payment of the lump sum
          amount provided for in this section 4.6(a), the Company shall
          have no further obligation to pay any benefits under this Plan.
          Notwithstanding the foregoing, if a Participant has less than
          five years of Continuous Service as of the date of the Change of
          Control, the amount paid to such Participant under this Section
          4.6(a) shall equal (i) the amount described in the first sentence
          of this Section 4.6(a) times (ii) a fraction, the numerator of
          which is the number of years and fractions thereof of the
          Participant's Continuous Service as of the date of the Change of
          Control and the denominator of which is five.

                                   -7-

     (b)  In the event a Change of Control of the Company occurs after the
          Participant's death and whether or not a benefit shall have then
          become payable to the Participant's Surviving Spouse, the Company
          shall pay to such Participant's Surviving Spouse, if then living,
          the present value of the unpaid Surviving Spouse benefit.  Upon
          payment of the lump sum amount provided for in this section
          4.6(b), the Company shall have no further obligation to pay any
          benefits under this Plan.  Notwithstanding the foregoing, if a
          Participant had less than five years of Continuous Service as of
          the date of his or her death before the Change of Control, the
          amount paid to such Participant Surviving Spouse under this
          Section 4.6(b) shall equal (i) the amount described in the first
          sentence of this Section 4.6(a) times (ii) a fraction, the
          numerator of which is the number of years and fractions thereof
          of the Participant's Continuous Service as of the date of death
          and the denominator of which is five.

     (c)  For purposes of this Plan, a "Change of Control of the Company"
          shall mean:

               (1)  The acquisition by any individual, entity or group
               (within the meaning of Section 13(d)(3) or 14(d)(2) of the
               Securities Exchange Act of 1934, as amended (the "Exchange
               Act")) (a "Person") of beneficial ownership (within the
               meaning of Rule 13d-3 promulgated under the Exchange Act) of
               20% or more of either (A) the then outstanding shares of
               common stock of the Company (the "Outstanding Company Common
               Stock") or (B) the combined voting power of the then
               outstanding voting securities of the Company entitled to
               vote generally in the election of directors (the
               "Outstanding Company Voting Securities"); provided, however,
               that for purposes of this subsection (1), the following
               acquisitions shall not constitute a Change of Control:  (I)
               any acquisition directly from the Company, (II) any
               acquisition by the Company, (III) any acquisition by any
               employee benefit plan (or related trust) sponsored or
               maintained by the Company or any corporation controlled by
               the Company or (IV) any acquisition pursuant to a
               transaction which complies with clauses (A), (B) and (C) of
               subsection (3) of this Section 2; or

               (2)  Individuals who, as of the date hereof, constitute the
               Board (the "Incumbent Board") cease for any reason to
               constitute at least a majority of the Board; provided,
               however, that any

                                   -8-

               individual becoming a director subsequent to the date
               hereof whose election, or nomination for election by the
               Company's shareholders, was approved by a vote of at least
               a majority of the directors then comprising the Incumbent
               Board shall be considered as though such individual were a
               member of the Incumbent Board, but excluding, for this
               purpose, any such individual whose initial assumption of
               office occurs as a result of an actual or threatened
               election contest with respect to the election or removal
               of directors or other actual or threatened solicitation of
               proxies or consents by or on behalf of a Person other than
               the Board; or

               (3)  Consummation by the Company of a reorganization,
               merger, share exchange or consolidation or sale or other

               Company or the acquisition of assets of another corporation
               (a "Business Combination"), in each case, unless, following
               such Business Combination, (A) all or substantially all of
               the individuals and entities who were the beneficial owners,
               respectively, of the Outstanding Company Common Stock and
               Outstanding Company Voting Securities immediately prior to
               such Business Combination beneficially own, directly or
               indirectly, more than 60% of, respectively, the then
               outstanding shares of common stock and the combined voting
               power of the then outstanding voting securities entitled to
               vote generally in the election of directors, as the case may
               be, of the corporation resulting from such Business

               Combination (including, without limitation, a corporation
               which as a result of such transaction owns the Company or
               all or substantially all of the Company's assets either
               directly or through one or more subsidiaries) in
               substantially the same proportions as their ownership,
               immediately prior to such Business Combination of the
               Outstanding Company Common Stock and Outstanding Company
               Voting Securities, as the case may be, (B) no Person
               (excluding any employee benefit plan (or related trust) of
               the Company or such corporation resulting from such Business
               Combination) beneficially owns, directly or indirectly, 20%
               or more of, respectively, the then outstanding shares of
               common stock of the corporation resulting from such Business
               Combination or the combined voting power of the then
               outstanding voting securities of

                                   -9-

               such corporation except to the extent that such ownership
               existed with respect to the Company prior to the Business
               Combination and (C) at least a majority of the members of
               the board of directors of the corporation resulting from
               such Business Combination were members of the Incumbent
               Board at the time of the execution of the initial
               agreement, or of the action of the Board, providing for
               such Business Combination; or

               (4)  Approval by the shareholders of the Company of a
               complete liquidation or dissolution of the Company.

     Notwithstanding the foregoing, neither the approval by the
     shareholders of the Company, nor the consummation, of the transactions
     contemplated by that certain Agreement and Plan of Merger, dated as of
     August 24, 1997, by and among Wausau Paper Mills Company, WPM
     Holdings, Inc. and the Company on substantially the terms and
     conditions set forth therein as of August 24, 1997 shall constitute a
     Change of Control for purposes of this Agreement.

     (d)  For purposes of this Plan, the term "Interested Shareholder"
          shall mean any person (other than the Company or any of its
          subsidiaries or any member of the Board of Directors as of the
          effective date of this Plan or any affiliate of such person) who
          first became the beneficial owner of 10% or more of the combined
          voting power of the Company's then outstanding securities after
          the effective date of this Plan.

     (e)  For purposes of this Plan, the present value of a Participant's
          retirement benefit or the Surviving Spouse benefit shall be
          determined by reference to the 1983 Individual Annuity Mortality
          Table with an assumed interest rate equal to the "immediate
          annuity rate" as then in effect as determined by the Pension
          Benefit Guaranty Corporation and promulgated in Appendix B to 29
          C.F.R. <section>2619.65 or any successor regulation adopted for
          the same or substantially similar purpose.

 Plan, a Participant's or Surviving Spouse's, as applicable, eligibility
 for benefit payments under the Plan is expressly subject to the following
 terms and conditions:

     (a)  The Company is and shall be entitled to the sole benefit and
          exclusive ownership of any inventions or improvements in plant,

          customer or price lists,

                                  -10-

          trade secrets and other things of similar type or nature used in
          the business of the Company that may be made or discovered by a
          Participant while he is employed by the Company, or, after the
          termination of his employment period if arising out of his
          activities, knowledge or experience gained while in the
          employment of the Company.  In the event that a Participant,
          during or after the termination of his employment, discloses
          all or any portion of the list of the Company's customers or the
          Company's pricing structure or all or any portion of the
          Company's manufacturing process or any other trade
          secrets or confidential information to any person, firm,
          corporation, associations or other entity for any reason or
          purpose whatsoever, no payment of any benefit otherwise due the
          Participant or his Surviving Spouse pursuant to this Plan shall
          be made by the Company.

     (b)  In the event a Participant, without the prior written consent of
          the Company and within a period of two years beginning on the
          first day following the Participant's termination of employment
          with the Company, directly or indirectly owns, manages, operates,
          joins, controls, is employed by or participates in the ownership,
          management, operation or control of, or is connected in any
          manner with, any business of a type and character which, in the
          opinion of the Company, results in the Participant then being
          engaged in the field of activities in which he was engaged by the
          Company at the time of termination (and within one year prior to
          said termination) and such business is, in the opinion of the
          Company, in direct or indirect competition in any market area
          served by the Company with any business then conducted by the
          Company in such market area, no payment of any benefit otherwise
          due the Participant or his Surviving Spouse pursuant to this Plan
          shall be made by the Company if the Participant fails to cease
          such activity within fifteen days of the mailing to him by the
          Company of the Company's opinion that he is in violation of the
          restrictions contained in this section 4.7(b).

     (c)  The Company shall have sole discretion to stop payment of any
          benefit or refuse to make payments otherwise due the Participant
          or his Surviving Spouse pursuant to this Plan if the
          Participant's termination of employment with the Company or his
          appointment to a position with the Company as other than an
          Executive Officer was by reason of or because of the
          Participant's fraud, embezzlement, misappropriation or

                                  -11-

          similar offense against the Company or any other state or
          federal felony offense.

     (d)  Subject to the provisions of section 6.2, no benefit shall be
          payable under this Plan to any Participant or Surviving Spouse
          who, for any reason, is not eligible for and does not receive a
          benefit under the provisions of the Retirement Plan.

     4.8  INALIENABILITY OF BENEFITS.  A Participant's right to a benefit
 under the Plan shall not be subject to voluntary or involuntary sale,
 pledge, hypothecation, transfer or assignment by the Participant or by his
 personal representatives or heirs, or any other person or persons or
 organization or organizations succeeding to any of the Participant's
 rights and benefits hereunder.

     4.9  FACILITY OF PAYMENTS.  Any benefit payable hereunder to any
 person who is legally incapacitated may be paid to a court appointed legal
 representative of such person.

     4.10  CLAIMS PROCEDURE.  Each Participant or Surviving Spouse whose
 claim for benefits is denied, in whole or in part, shall be provided with
 a notice, written in a manner calculated to be understood by such person,
 setting forth the specific reasons for such denial and outlining the
 review procedure of the Company.  Each such Participant or Surviving
 Spouse shall be given a reasonable opportunity for a full and fair review
 by the Company of the decision by which the claim was denied.

                                  -12-

                             ARTICLE V
                      PROVISION FOR BENEFITS

     5.1  ASSETS OF THE COMPANY.  Benefits which become payable under the
 provisions of the Plan shall be paid directly by the Company out of its
 assets.  No assets of the Company shall be set aside or segregated for the
 provision of such benefit payments.  No Participant or Surviving Spouse,
 nor any other potential or actual recipient of benefits under the
 provisions of this Plan shall acquire any right, title or interest in the
 assets of the Company by reason of the Plan and, to the extent that the
 Participant, Surviving Spouse or such other recipient shall acquire a
 right to receive payments from the Company pursuant to the Plan, such
 right shall be no greater than the right of any unsecured general creditor
 of the Company.

                                  -13-

                            ARTICLE VI
               AMENDMENT AND TERMINATION OF THE PLAN

     6.1  AMENDMENT.  The Company reserves the right to amend the Plan from
 time to time and at any time, effective as of any specified current, prior
 or future date; provided, however, that no such amendment shall modify or
 reduce a Participant's accrued benefit as of the date such amendment is
 adopted.

     6.2  TERMINATION.  The Company reserves the right to terminate the
 Plan at any time and for any reason; provided, however, that upon
 termination, each Participant's accrued benefit shall be fully vested
 subject only to the provisions of section 4.7.  A Participant's "accrued
 benefit" shall mean the benefit which would be paid or payable pursuant to
 this Plan following the Participant's termination of employment if the
 Retirement Plan had terminated as of the same date on which the
 termination of the Plan occurs (and provided for payment of accrued
 Retirement Plan benefits upon the Participant's termination of employment)
 multiplied by a fraction, the numerator of which is a Participant's years

 of Continuous Service recognized under section 3.2 and the denominator of
 which is ten.

                                  -14-
